Title: Method and device for controlling shape in rolling mill
Inventor: KOKUBO MISAO
IPC: B21B37/32
Filed: 1994-09-28
Abstract: PURPOSE: To improve control precision for a plate shape and to stabilize it by predicting the plate shape of a rolling stock after a unit time is elapsed and, based on its deviation against a target plate shape, controlling the spraying condition of a cooling medium. CONSTITUTION: A detection signal (y) for a plate shape of a rolling stock, which is detected by a shape detecting means 14, and a control signal (u) of a cooling mechanism 11 are inputted in a shape predicting means 16. When a rolling mill 10 is cooled by the cooling mechanism 11 under the same conditions, the predicting means 16 predicts the plate shape y(t+1) of the rolling stock after a unit time is elapsed. A comparison is made between a target plate shape yo and the predicted plate shape y(t+1) by a comparing means 18, and the cooling mechanism 11 is controlled by a controller 20 so that a deviation εmay be eliminated. Thus, a shape change is promptly dealt with, and overshoot for example is prevented.

Title: Method for measuring temperature of hot molten material
Inventor: KISHU TAKAFUMI
IPC: G01J5/00
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the temperature of a hot molten material can be measured stably for a long period. SOLUTION: At the time of measuring the temperature of a hot molten material, a temperature measuring instrument 1 is moved to a temperature measuring position immediately above a tundish 14. The detecting section 3 composed of the optical fiber of a radiation thermometer 2 is housed in a guide tube 8 and the front end of the section 3 is protruding from the tube 8 by 0-30 mm. Then the guide tube 8 is positioned above the surface of molten steel 13 so as to prevent the tube 8 from coming into contact with the surface of the molten steel 13 and stopped and maintained perpendicularly to the surface of the molten steel 13. Then the detecting section of the instrument 1 is dipped in the molten steel 13 so as to measure the temperature of the molten steel 13 by rotating a pinch roll 10 in the normal direction.  After measurement, the detecting section 3 is pulled up from the molten steel 13 and housed in the tube 8 as quickly as possible.

IPC: G06F15/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To eliminate artificial operation and stably set a masking region in an appropriate range by getting an image of a subject having a circular part for outputting as an image signal, detecting at least a part of the circular part, and setting the masking region of the subject using a basic coordinate and a distance obtained by an arithmetic means. SOLUTION: An image pick-up device 33 gets an image of a carried PVC sheet, while a signal pre-processing part 2 connects to an output side of the device 33 for A/D conversion or the like. An image memory 3 acquires a signal obtained by the signal pre-processing part 2. A coordinate detecting part 4 detects an edge of a pocket based on image data acquired into the image memory 3 to detect x, y-coordinates. A radius and center coordinate calculating part 5 uses the coordinates x, y output from the coordinate detecting part 4 to calculate a radius and a center coordinate. A mask creating part 6 stores the radius and the center coordinate calculated by the calculating part 5, thereafter sets a masking region based on the radius and the center coordinate, and performs masking on the PVC sheet with subsequent tablets supplied.

Title: Method and apparatus for measuring over- lap length of material strip piece
Inventor: HORUSUTO ZERUGERU
IPC: G01B21/06
Filed: 1992-09-01
Abstract: PURPOSE: To correctly measure an overlapping length by detecting a tip of a material string piece on a drum and simultaneously measuring an angle position of the drum at this time. CONSTITUTION: A material string piece 2 mounted on a supplier 1 is wound around a drum 3 after the supplier 1 and the drum 3 are started, wherein a previous end A of the piece 2 is detected by a detector 5 at this time.

After the string piece 2 is completely wound, its end passes through the detector 5, and a corresponding signal in the detector and an angle position of the drum 3 at this time are also detected and provided to the unit 6. Both measured values are evaluated in the unit 6, and a complete rotation angle of 360 degrees of the drum 3 is subtracted to form a difference relating to both angle measurements, thereby allowing the unit 6 to directly detect an overlapping length.

Abstract: PURPOSE:To enable the easy adjustment of steering wheel height by providing a telescopic fluid cylinder among a plurality of stems so fitted in a vertical direction to a steering wheel axis as to be freely rotatable, and interlocking the piston rod thereof with an opposed stem. CONSTITUTION:A plurality of stems 23 is so provided for the boss 24 of a steering wheel axis 20 as to be movable vertically, and the upper end of the stem 23 is slanted in an expansionary way for fixing to a grip 22.

Title: Ink dot printer
Inventor: OKUNO SHIGERU
IPC: B41J2/305
Filed: 1984-11-07
Abstract: PURPOSE:To avoid the entry of nozzle into the drive section of needles as well as eliminate the failure of connection by the intrustion of ink into connecting interpositions by a method in which electrical connection to needles is made on nthe rear end side, and the polarity is positioned on the ground side. CONSTITUTION:Electric connecting point on the needle 24 side is a press spring 37 made of a ferrosilicon steel plate, having an electric conductivity. The needle 24 is made of stainless steel having electric conductivity. Electric field is produced between an electrode 47 and the tip of the needle 24 to fly ink 43 electrostatically. In this case, however, stable electric field and stable needle action can be obtained without any influence by staining with ink, as compared with the case where electric connecting point to the needle is set up on the tip of the needle. The polarity on the needle 24 side is set on the ground side. Since the surrouding of the drive section 17 including a coil 20 is the ground electrically, the level of noise to be entered can be lowered and its influence can be greatly reduced. Stable printing conditions can thus be obtained without disturbance of signal pulse.

Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To deaden the force of molding material flow by forming the material inflow ports of respective secondary runners, so that the material inflow ports are outside the extension region of a primary runner in the part not narrower than the prescribed opening area of the material inflow ports. SOLUTION: The surrounding wall 8a of a material collection 8 is arranged in the extension direction of a primary runner 7.
